"Body area network" sounds like something from a 1970s sci-fi movie, but is actually the subject of serious R&D by major players. Biosensors that collect and wirelessly transmit data from human bodies have clear applications in healthcare and other areas, but the need for ultralow power is even more of a challenge than in …

Data gathering, or medication control.
I can see that this will be used for all sorts of thing in the medical world, but that in itself is worrying.
Lets make an assumption that it may allow feedback controlled drug release for people with chronic pain or insulin dependence.
It would appear to me that no longer would your private data be at the mercy of the security of the network, but your very life. Imagine if a 'hacker' could gain access, and trigger an overdose of whatever drug is being dispensed, it might be more serious.
(BTW for all you big-brother conspiracy theorists, consider a scenario where somebody could release drugs remotely to calm a crowd).
This already exists - self medicating pain relief of the 'press this button to get some' variety. There is, of course, a separate system that limits the amount that can be released within a given time box, so it's impossible to overdose yourself (or have a 'hacker' do it to you).
